PADDLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 618,295, dated January 24, 1899.

Application filed December 29, 1897. Serial No. 664,210. (No model.)

To all whom it may concern: nals of the paddle-blades. The greater the Be it known that I, ROBERT SOHLEGEL, a distance between these axes or shafts the citizen of the United States, residing in the greater the distance of the journal-supports city and county of San Francisco, State of of the blades from each other and the con- 55 California, have invented an Improvementin sequent strength of the supports, which en- Feathering Paddle-W'heels; and I hereby deables me to make the blades of as greatalength clare the following to be a full, clear, and as may be desired. exact description of the same. The blades E are made of any suitable or My invention relates to that class of wheels desired form or material. In Figs. 4., 5, and '60 known as feathering paddle-wheels and in 6 I have shown these blades made either onwhich the blades or floats of the Wheel are tirely of metal with atruss-framein the upper made to dip into the water and pass through part and metal blade at the lower end or they the arc of rotation while they are within the may be made of a metal frame and wooden water and until they rise out of it without buckets suitably fixed to this frame and re- 15 changing their essentially vertical position, placeable whenever broken.

These pins may be of alength with each other, journal-pins upon the pesufficient to extend approximately across the 25 ripheries of the disks, and floats or blades so full width of the blades, or the blades may be connected with said journal-pins as to be made narrower and beveling outwardly tomaintained in essentially the same plane durward the disks 0 to form a narrower journal ing the revolution of the wheel, said blades for the pins which project from these disks. being also so constructed as to dip into the The blades maybe of any desired or conven- 8o 30 water through which the wheel is moving ientlength belowthejournal-pins of the disks without the necessity of submerging the A, so that they project to a considerable diswheel-rims to such an extent as to create tance below thelowerperiphery of these disks frictional resistance to the revolution. and can thus be made to dip into the water,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a paddle-wheel, the combination of disks mounted upon the ends of horizontallyjournaled shafts, one of said shafts located above the line of the other and said shafts connecting with their respective disks from opposite sides to provide a clear space between them, pinsfixed in the opposing faces of the disks, and extending in opposite directions across the said space, and blades each journaled upon two pins projecting from the disks, whereby the blades are maintained in a vertical position during the revolutions of the wheel.

2. In a paddle-wheel, the combination of opposing disks, horizontally-journaled shafts therefor and connecting with their respective disks from opposite sides, to provide a clear space between them, blades having journaled boxes extending through them, and pins on the disks to fit said boxes, said pins of each disk extending toward the companion disk and terminating short of the latter and one pin of each disk adapted to journal in one box of each blade.

3. In a paddle-wheel, the combination of opposing disks, horizontally-journaled shafts located one above the line of the other and connecting with their respective disks from opposite sides, to provide a clear space between them, and blades within said space and pivotally connected with opposing disks.

at. Paddle-wheel blades having a vertical length greater than their width and consisting of a truss-frame having horizontal journal-boxes extending through the upper and lower ends, with blades fixed to and extending downwardly from the frames, disks fixed upon horizontally-journaled shafts, out of line with each other and having an open space between them, and pins projecting from the rims of the opposing disks and entering the journal-boxes of the paddle-blades.

In witness whereof I have hereunto set my hand.

ROBERT SCHLEGEL.
